After a special beetle from this SCP is killed by a human (on purpose, anomalous properties do not take place if the killing was accidental) their house is infested with these beetles. I'm thinking this original beetle looks different from the rest, perhaps a different color. The infestation starts small but quickly explodes into conditions that render the building condemnable. These infesting beetles can be killed by anyone with no repercussions. These beetles reproduce through laying unprecedented amount of eggs asexually and can do so wherever water is present, even if said water is in minuscule amounts. The infesting beetles hold no anomalous properties other than their unusual reproductive factors and can be killed by conventional means, smashing, pesticide, etc.

The eggs, however, are anomalous, and can only be reliably exterminated through immolation, due to their small size and extreme resistance to poison. They hatch and mature extremely quickly (matter of hours for hatching, minutes for maturing) and this process is increased even if the eggs are moved around during incubation. This means that the eggs will follow the homeowner if they move house do their pervasiveness. It should be noted, however, that the beetles will not infest another person's house and eggs will quickly die outside of the original host's home.

The ultimate goal is to lead to the death of the homeowner (original killer of the abnormal beetle), either through suicide, exhaustion, lack of nutrients due to the widespread presence of the beetles, or other means. The body is then used as an incubation chamber to spawn another instance of the original, abnormally colored beetle, which then searches for another who will kill it.

I plan on including a testing log that details the experiences a d-class has with this SCP.

Let me know what you think: if something like this has been done before, if it's interesting enough, what could be done, etc.

This sounds a tad stupid, in itself. Basically, the whole premise is that the beetle tries to get killed just to re-spawn another of its kind. That means that the whole population can only decrease (even more so that accidental death don't re-spawn another beetle) and thus, this species would quickly disappear. Hence, such a species could not naturally appear. Besides, who kills beetles (besides collectors and farmers) ? Make it a cockroach and then it would become more logical.

Unless it's a bioengineered creature. If it's a weapon (only purpose I see here given its effects), then it's a pretty inefficient one, you have to wait until the exhaustion of the target, which, given the effects, could take a long time.

However, this could be seen as a pretty sadistic punishment from some ecoterrorists, so it could be written that way and could even work (you could even introduce a new GoI, BTW).

It seems like an interesting idea, but there's a few problems that need to be addressed:

1: How is a new target selected besides some random guy stepping on it? Wouldn't it be more logical for the beetle to select who it's crushed by?
2: How many abnormally colored beetles are produced in a corpse? If its only one, then the species should die out pretty fast.
3: Why are the beetles so intent on destroying the structure the targeted person lives in? Wouldn't it make more sense to try to kill the person directly somehow, like poisoning their water or something?
4: Finally, how did this thing come into existence, and if it's artificial, what's the purpose of the beetles and the reasoning for the creator to make it?

I like the idea, don't get me wrong, but there's some serious flaws and plot holes that must be addressed.
